Everything a ghostwriter does. On your machine, once.

That is the right comparison. Reedsy, whose figures come from hundreds of completed collaborations on their marketplace, puts a ghostwritten novel at $5,000–18,000 for common genres like fantasy, sci-fi and adventure — roughly $0.15 a word — and it takes months. Dedicated ghostwriting agencies quote considerably more. Instawritr is a one-time purchase that produces the same deliverables — manuscript, cover, EPUB, audiobook, store-ready files — on your own machine, in about three hours of wall time, as many times as you like. You keep full commercial rights to everything it produces. The honest trade-off: a good ghostwriter brings judgement and originality that a pipeline does not, so this suits genre fiction and high-volume catalogues far better than it suits a single literary passion project.

Those are writing assistants — they help while you write, and you still do the writing, the formatting, the cover, the audiobook, the marketing assets and the store uploads. Instawritr is a publishing pipeline: it produces the finished, QA-scored artefacts — manuscript with human-like prose craft, cover, EPUB, full audiobook, and 30-day social launch bundle — and stages them to 6 stores. The difference is not the prose model, it is everything around the prose. If you only need help drafting, a chat assistant is cheaper and better at it.

Yes — 24 to 40 chapters, 80,000 to 120,000 words, coherent from start to finish. A story bible plus an open-loop ledger keep characters, clues and cliffhangers consistent across 30+ chapters, while human-like prose engineering removes repetitive AI tropes and enforces voice consistency so chapter 38 is written with the same craft and context quality as chapter 3.

Yes. Set your target length and the whole pipeline scales to match — from a 5,000-word short story to a 120,000-word novel, same pipeline, same QA loop. Chapter count and every gate derive from your target, so a short comes out as a tight few-chapter piece, not a padded novel (a 5,000-word test story scored 98/100 after the QA pass). A built-in duplicate tracker also stops it from accidentally writing the same book twice.

Yes — Series Mode generates an entire multi-book series, one command per book. A persistent series bible carries characters, world, timeline and open plot threads across books, and a blocking canon gate re-checks every new book against series canon and repairs contradictions before the book ships, so book 3 cannot contradict book 1. Locked cover DNA gives the series matching covers and every EPUB carries series metadata, so stores shelve the books as one series. In live validation a 2-book series passed the quality gate at 94/100 on both books with zero canon contradictions. Series Mode is exclusive to Instawritr Pro Plus ($249) — Pro ($149) does not include it.

Yes. The pipeline narrates the whole book with open-source Kokoro TTS at zero per-word cost — retail-spec per-chapter MP3s plus a chaptered .m4b with opening and closing credits and a ~3-minute retail sample. AI narration is disclosed honestly per store.

A finished book sitting on bookstores sells nothing without discovery. Instawritr automatically mines emotional peak scenes, punchy quotes, and high-converting trope tags directly from the Story Bible and chapter summaries created during the run — spending zero extra reading tokens. It generates a 30-day social rotation calendar, renders multi-aspect SVG promo cards (Trope Carousels, Quote Cards, and Book Promos), and compiles vertical 9:16 MP4 video teasers (with Ken Burns camera motion and kinetic typography) ready for TikTok, Instagram Reels, and YouTube Shorts.

Ebook (EPUB): Apple Books, Google Play, Kobo and Barnes & Noble. Audiobook: Spotify for Authors and InAudio. Honest AI disclosure is handled per store. (Audible/ACX is excluded because it requires human narration.)

No. You need Python 3.11+, the Pi CLI and a Gemini key (or a local llama.cpp model); the audiobook stage needs ffmpeg. After you buy on Whop you get a GitHub invite, then you open Pi and say "Set up Instawritr for me" — it installs itself. No repos or CLIs to wrangle.

Yes. Personal and commercial use of everything the pipeline produces is unrestricted and royalty-free. (You may not resell or redistribute the harness code itself.)

Neither. Instawritr is a one-time purchase and bring-your-own-key. You pay your own model provider directly — or nothing at all, running fully local via llama.cpp. No credits, no subscription, no vendor policing your content.

About 3 hours of wall time for a full novel on a standard connection. The pipeline is engineered like software — fully resumable if interrupted, with word-floor gates, plan-coverage gates, retries and circuit breakers built in.

14-day refunds. If the factory is not for you, you are covered.
